Ingredients

Red Onions – The key ingredient of this onion marmalade is red onions. If they are not available, then you can use white onions or yellow onions too. Having said that, the result is better with red onions as they are sweeter and also have thicker flesh and skin than white onions.

Brown Sugar – Brown sugar adds a nice caramelized taste and earthy sweetness to the marmalade.

Apple Juice – Apple juice is used to cook the jam and also gives it a slight sweetness. You can use packaged or homemade juice.

You can also replace apple juice with pineapple juice or orange juice.

Red Pepper Flakes – You can adjust the red pepper flakes as per your taste.

Red Wine Vinegar – It gives a nice tang that complements the sweetness of the marmalade very well.

You can replace it with apple cider vinegar, balsamic vinegar, or white wine vinegar too.

Others – You will also need salted butter, light olive oil, garlic cloves, salt, and black pepper powder.

To make the marmalade vegan, replace butter with light olive oil.

Herbs like thyme or rosemary can be added to this recipe for extra flavor.

Adding a splash of bourbon or sweet red wine to the almost-ready recipe takes it to another level.

Frequently Asked Questions

Pro Tips By Neha

Always thinly and evenly slice the onions, as they cook evenly and get caramelized properly.

Cook the onions on low heat, so that they do not get brown faster. Also cooking on high heat has more chance of burning the onions.
